Hi! This is my first post. I am SERIOUSLY considering throwing my PC away and buying an 8-core MP. But I don't know if I will need a better sound card. Sorry, I tried researching this up but I'm still confused. Is the sound card in the MP good enough? I am not a musician, I just want good fidelity for music, and stereo is all I want. I have a Creative (guess it's the SBLive) today in my PC. What type of output connectors does the MP have? I saw posts mentioning optical, but I have 2.1 Altec Lansing baffles and I'd like to continue using them. They do NOT have optical input. Just the normal mini-stereo adapter. I also suppose there is some kind of microphone input somewhere, I need it for skype VOiP (hope it works well on OS X). Sorry for asking the basics. I hope I can join the Mac community soon! Thanks a lot!
